MChip_Fault
Chip error (AC)
ID037
AuxPowerFault
Auxiliary power error
ID038
InvSoftStartFail
Inverter failed to output
ID041
RelayFail
Relay detection failure
ID042
IsoFault
Low insulation
impedance
Check the insulation resistance between the
photovoltaic array and ground (ground), if
there is a short circuit, the fault should be
repaired in time.
ID043
PEConnectFault
Ground fault
Check ac output PE wire for grounding.
ID044
InputConfigError
Error setting input
mode
Check the input mode (parallel/independent
mode) Settings for the inverter. If not,
change the input mode.
ID045
CTDisconnect
CT error
Check whether the CT wiring is correct.
ID046
Reversal Connect
The battery is
connected reversedly
Check whether the battery wiring is correct.
ID047
Parallel Fault
Master does not exist or
is duplicate
Check the parallel mode settings for the
inverter. Check whether the wiring is
correct.
ID048
SNTypeFault
Serial number fault
Internal faults of inverter, switch OFF
inverter, wait for 5 minutes, then switch ON
inverter. Check whether the problem is
solved.
If no, please contact technical support.

TempFault_Bat
Battery temperature
protection
For Inner BMS battery, make sure that the
battery NTC cable is properly connected.
Make sure the inverter is installed where
there is no direct sunlight.
Please ensure that the inverter is installed in
a cool/well ventilated place.
Ensure the inverter is installed vertically
and the ambient temperature is below the
inverter temper ature limit.

PVOVP
PV over-voltage
Check whether the PV series voltage (Voc)
is higher than the maximum input voltage
of the inverter. If so, adjust the number of
PV modules in series and reduce the PV
series voltage to fit the input voltage range
of the inverter. After correction, the inverter
will automatically return to its normal state.
